**agrin04**, Sunday, February 27, 2011 at 11:08am1 rotation = 2pi

1/8 rotation = 1/8 x 2pi = pi/4

State y as the height difference created from the rotation of the wheel and the bottom of the ferris wheel (not the ground)

height = y + 1

= r - r cos {(2pi/20)t - (pi/4)} +1

= r(1 - cos pi{(t/10) - (1/4)}) +1

= 10(1 - cos pi{(t/10) - (1/4)}) +1
